| unused (0)
13. This flag is "1" if a interrupt request has been sent to the Z80 and it has not yet been acknowledged by the Z80. (A interrupt request is sent by the GA for standard CPC raster interrupts or by the ASIC for raster or dma interrupts).
14. This is a counter internal to the GA and counts the number of HSYNCs since the start of the VSYNC and it is used to reset the interrupt counter to synchronise interrupts with the VSYNC. This counter counts up. This value is between 0 and 2. If this value is 0, the counter is inactive. If this counter is 1 or 2 the counter is active .
Immediatly following the memory dump there is optional data which is seperated into chunks.
